"The first thing I notice (and appreciate) about the Rare Beauty Perfect Strokes Matte Liquid Liner ($19) is how smooth the application is. It seems almost like the pen glides over my eye without me even having to do any work. The tip of the pen itself is also pretty firm, which makes creating a wing with a super-sharp tip a lot easier than with other products. And before you ask — yes, it's also smudge-proof." — Danielle Jackson, assistant beauty editor
